摘　　要：在过饱和状态下,交通流的特征异常复杂,缺乏稳态交通流的概念.为改进城市路网交通的动态管控,引入模型预测控制(Model Predictive Control, MPC)方法.将动态扰动建模纳入MPC框架中,以更好地应对实际交通流的变化;通过改进存储-转发机制,建立更准确的区域交通模型,更贴近实际排队长度;提出一种分层优化的区域交通协调管控方法,以应对过饱和路网交通的挑战,为缓解网络局部交通拥堵、提升路网交通运行效率提供理论支持.In over-saturated conditions where the characteristics of traffic flow are extremely complex and lack the concept of steady-state traffic flow.In the face of dynamic disturbances,real-time and effective management of oversaturated urban road network traffic becomes an important task.In this study,we introduced the Model Predictive Control(MPC)method to improve the dynamic management of urban road network traffic.We incorporated modeling of dynamic disturbances into the MPC framework to better cope with changes in actual traffic flow.At the same time,by improving the store-and-forward mechanism,we established a more accurate regional traffic model that is closer to the actual queue length.Finally,we proposed a hierarchical optimization method for coordinated management of regional traffic to address the challenges of over-saturated road network traffic.This research not only provides theoretical support for alleviating local traffic congestion and improving the efficiency of road network traffic,but also has important application prospects in practice.
